org.lsst.ccs.subsystems.fcs.FilterIdentificator

public class FilterIdentificator
extends Object

This is a Model for the system which identifies filters on the autochanger trucks. On the autochanger trucks, we have hall effect sensors to identify filters. 3 sensors are on the truck X- and 3 sensors are on the truck X+. Each sensors gives a digital signal depending if there is a magnet in front of the sensors. Following the magnet combination, we can define 64 ID numbers (from 0 to 63). The location are named ID0, ID1 and ID2 on the X- side, and they are named ID3, ID4, and ID5 on the X+ side. The ID0 is the Least Significant Bit (LSB) The ID5 is the Most Significant Bit (MSB) cf document LCA-13492

Method Detail

getFilterId

@Command(type=QUERY,
         level=1,
         description="return filterId.")
public int getFilterId()

return filterId. Don't read sensors again.

Returns:

filterId

getFilterIDSensors

public List<DigitalSensor> getFilterIDSensors()

Return the list of filterID sensors. Used in simulation and for tests.

Returns:

updateFilterId

public void updateFilterId()

Update filterId from sensors values. If a sensor is ON, bit=1 and if sensor is off, bit = 0.
